Row heats and pressurizes and be plastically deformed it, the front end variant part 28 for covering hole is formed, so as to contact step by circuit substrate
The upper surface in portion 25 and front end variant part 28 in the height direction fix distance light substrate 14.Using foregoing hot riveting with convex
Platform 24a~24d carries out hot riveting to distance light with heat sink 51, so as to contact upper surface and the hot riveting of stage portion 26 by heat sink
Distance light heat sink 51 is fixed in the height direction with boss 24a~24d.
It is formed on top plate 21, is kept by heat sink with convex as shown in figure 8, heat sink holding boss 23a, 23b are protruded
Platform 23a, 23b are kept with heat sink 51 with substrate 14 and distance light to distance light and ensure there is gap 31 between.
The rear side coating conducting-heat elements 30 in region in gap 31, being equipped with the first LED18a, thus clamp the conducting-heat elements 30
Rolled in distance light with substrate 14 with distance light between heat sink 51 and to the conducting-heat elements 30 in the way of being contacted with the two.
As described above, in the present embodiment, heat sink holding boss 23a, 23b are multistage shape, the heat sink connects
Touch thickness of the difference in height equivalent to distance light heat sink 51 and gap 31 that stage portion 26 contacts stage portion 25 with circuit substrate
Apart from sum.Therefore, circuit substrate contact stage portion 25 is as being located at distance light between substrate 14 and distance light heat sink 51
Keep the distance piece function at the interval in gap 31.
In the present embodiment, heat sink holding is also shaped in distance light reflector with boss 23a~23c by resin
The top plate 21 of unit 16, can carry out the processing of the high-precision shape of several units of micrometers, additionally it is possible to make manufacturing process and construction
Simplify and realize cost degradation.In addition, distance light substrate 14, the shape simplification of distance light heat sink 51 can be made, it can pass through
Punch process is molded to heat sink, and cost degradation is realized therefore, it is possible to simplify manufacturing process and construction.Further, lead to
Cross heat sink holding and to be set to hot riveting stage portion 27 with boss 23a~23c front end, thus, it is possible to using hot riveting as remote
The fastening linking method of light substrate 14, and the simplification of the reduction, miniaturization, manufacturing process of number of components can be realized.
Therefore, in the lamps apparatus for vehicle 10 of present embodiment, distance light substrate 14 can be ensured with simple structure
The gap 31 of surface and distance light between heat sink 51, and can by configure the conducting-heat elements 30 of coating-type and ensure insulation
Property and thermal conductivity.Thereby, it is possible to prevent circuit substrate produced during using preshaped thermally conductive sheet, thermal component from sticking up
Song, and can prevent light-emitting component from deviateing from the focal position of reflector and causing light distribution characteristic to be deteriorated.
(the 6th embodiment)
Although exemplified as lamps apparatus for vehicle 10 many lamp-type in the embodiment of first embodiment~the five
Light fixture, also can be with simple structure even if using the structure of other optical systems such as projection type, PES types, parabolic shape
And ensure the gap between the surface of circuit substrate and thermal component, and can be ensured by configuring the conducting-heat elements of coating-type
Insulating properties and thermal conductivity.In addition, circuit substrate produced when can prevent from using preshaped thermally conductive sheet, thermal component
Warpage, and can prevent light-emitting component from deviateing from the focal position of reflector and causing light distribution characteristic to be deteriorated.
The present invention is not limited to above-mentioned each embodiment, can be carried out in the scope shown in claims various
Change, by that will distinguish that disclosed technological means is appropriately combined in various embodiments and the embodiment that obtains, is also wrapped
In the technical scope for being contained in the present invention.
